    A tube, open at the left end and closed at the right, has standing-wave patterns at frequencies of 198 Hz and 330 Hz. The speed of sound in air is 343 m/s. The lowest two harmonics (normal modes) that these two standing waves could be are m = and The frequency of the fundamental (m = 1) is Hz. The wavelength of the fundamental mode is m. The tube is m long

    Discuss why it is only possible to produce the odd harmonics in a system with one open end and one closed end (pictures will help!). Write down the relation between An and L for the n 1, 3, 5, and 7 harmonics, and calculate the wavelength and frequency of the fundamental resonant mode for L 0.875 m and f 686 Hz. Then calculate the wave velocity of this oscillation. Pipe with one open and one closed end Only the odd...

    A tube 1.20 m long is closed at one end. A stretched wire is placed near the open end. The wire is 0.330 m long and has a mass of 9.60 g. It is fixed at both ends and vibrates at the second harmonic. This sets the air column in the tube into oscillation at its fundamental frequency by resonance. (a) Find the frequency of oscillation of the air column and (b) the tension in the wire

    BACK NEXT Chapter 17, Problem 050 GO A tube 1.30 m long is closed at one end. A stretched wire is placed near the open end. The wire is 0.351 m long and has a mass of 9.70 g. It is fixed at both ends and oscillates in its fundamental mode. By resonance, it sets the air column in the tube into oscillation at that column's fundamental frequency. Assume that the speed of sound in air is 343 m/s, find...

    part 1. A 9.00-m long string sustains a three-loop standing wave pattern as shown. The string has a mass of 45 g and under a tension of 50 N. a. What is the frequency of vibration? b. At the same frequency, you wish to see four loops, what tension you need to use. Part 2. a. Determine the shortest length of pipe, open at both ends, which will resonate at 256 Hz (so the first harmonics is 256Hz). The speed...
